参数签名

描述

该算子 moments_gray_planemoments_gray_planeMomentsGrayPlaneMomentsGrayPlaneMomentsGrayPlanemoments_gray_plane calculates the gray value moments and the parameters of the approximation of the gray values by a plane. The calculation is carried out according to the following formula: where is the plane, , the center, and , , and the scaled moments of 区域区域区域区域区域区域.

The parameters AlphaAlphaAlphaAlphaalphaalpha, BetaBetaBetaBetabetabeta and MeanMeanMeanMeanmeanmean describe a plane above the region: Thus AlphaAlphaAlphaAlphaalphaalpha indicates the gradient in the direction of the line axis (“down”), BetaBetaBetaBetabetabeta the gradient in the direction of the column axis (to the “right”).

注意

Note that 该算子 moments_gray_planemoments_gray_planeMomentsGrayPlaneMomentsGrayPlaneMomentsGrayPlanemoments_gray_plane only considers the given 区域区域区域区域区域区域 and ignores any previously set domain of the input image ImageImageImageImageimageimage.

运行信息

• 多线程类型:可重入(与非独占操作符并行运行)。
• 多线程作用域:全局(可以从任何线程调用)。
• 在元组级别自动并行化。

结果

该算子 moments_gray_planemoments_gray_planeMomentsGrayPlaneMomentsGrayPlaneMomentsGrayPlanemoments_gray_plane 返回值 2 ( H_MSG_TRUE) if an image with the defined gray values ('byte'"byte""byte""byte""byte""byte") is entered and the parameters are correct. The behavior in case of empty input (no input images available) is set via 该算子 set_system(::'no_object_result',<Result>:)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>), the behavior in case of empty region is set via set_system(::'empty_region_result',<Result>:)set_system("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)set_system("empty_region_result",<Result>). If necessary an exception is raised.
